APPARATUS non FASTENING PAIL oovnns.

Application filed August 5, 1926. Serial No. 127,370.

This invention relates to improvements in apparatus for fastening pailcovers, an obin the following specification, reference be-. ing had to the accompanying drawings, inv

which 7 Figure 1 is a side elevation of the improved apparatus.

Figure 2 is a plan view.

Figure 3 is-a' detail sectional view taken on the line 3 3 of Figure 2.

This invention is an improvement on the apparatus for fastening steel pail tops disclosed inmy Patent 1.443,264 of January 23, 1923 to which, and also my Patent 1,459,469 of June 19, 1923, reference may be made to the details of the crimping mechanism. This mechanism will bear brief. description here so that the purpose of the improvement may readil I be understood.

The crimping .mec anism comprises a cover crimpin head com rising a base plate 1 with a stan ard 2 in t e middle. A plu-' rality of arms 9 are formed with crimping jaws 10 at one side of the pivotal mountmg at 11 upon'brackets 12 of the base plate,

' the other side of the arms being connected with rods 6, the upper ends of which are joined with lugs 7 of a circular flange 5.

Pins 16 extending upwardly from a ring 17 pass, through suitable guiding elements 18 upon the base plate 1, and carry springs 19 which tend to hold the base plate 1 in a predetermined position in respect to the lugs 13 when the mechanism is set in the operative position upon the cover C of the pail P.

Downward movement of the circular flange 5 upon'the standard 2 will rock the arms 9 to perform a-crimping' operation upon the lugs 13.

Tt is the purpose of the present invention to make it possible to handle and operate the fore oing crimping mechanism, or closadvantage. The resulting ing comprises the following structure: A platform 20 has a rigid standard 21 at one end provided with-a set collar 22 upon which the sleeve at one end of the arm 23 formis slidable.

as 1t 1s sometimes called, to better y movable mounting a supporting and guiding frame for the crimping head a're swivelled for transverse swinging movement of the arm with its crimping head. -A second set collar 24 near, the top of the rigid standard holds the frame 23 down in place. A hook 25, pivotally mounted at 26 upon the set collar 24 may be swung over into engaging .position with the top of the frame 23 to keep the latter from swinging when in the operative position, and when desiring to move the apparatus from place to place upon the floor.

For the latter pur ose the platform 20 has a pair of side wlieels 27 near one extremityand a pair of casters 28 near the other. The reader may understand that if the frame 23 were permitted to swing free the frame is held in position and the apparatus can readily be transported. The frame 23 is of bracket formation. The free extremity-thereof has a boss 29 in which the "standard 2 of the crimping mechanism The boss has a shoulder 30 with which a latch 31 is engageable. This latch is pivotally mounted at 32 (Fig. 3) between the side bars 33 of a handle 34. A rod 35 connects the' latch with a pivoted member 36 upon the handle 34, depression of the latter swinging the latch, 31 away from the shoulder 30 to permit dropping. of the crimping mechanism upon the pail cover.

A collar 37 (Fig. 3) carries the circular flange 5 previously mentioned. This is swivelly mounted upon the flanged sleeve 38 of a head 39 which is movably mounted upon the standard 2. The head has a pair of latthe handle 33-34, which is capable of being.

raised and lowered or swung to one side or the other 1n order to place the crimping mechanismv wherever desired.-

stood. Prior to setting the pail upon the platform 20 the handle 34 is supposed to be swung around approximately from the position shown in Figures 1 and 2 making it possible to l set the pail down in a natural The operation may now be readily undermanner, rather than to necessitate sliding the pail in place upon the platform as is the case in machines of this character having a rigid crimping mechanism.

Having set the pail P down the handle 34 is swung around to bring the crimping mechanism in position over the cover C. The

crimping mechanism is carried by the frame- 23 and the entire frame swin s upon the rigid standard 21.. T cover C is supposed to have been laid in place. The operator then locates the crimping mechanism so that the crimping jaws l0 register with the lugs 13. The crimping mechanism can be spun around because of the swivel mounting of the collar 37 (Fig. 3) upon the flange of the sleeve 38.

manner disclosed in the foregoing patents.

Usually there are eight lugs upon steel covers as herein contemplated, but should the cover happen to have sixteen lugs, as is sometimes the case, the crimping mechanism has only to be raised by means of the handle 34 and given a one-sixteenth turn so that the next set of lugs can be engaged and crimped in the manner explained.

After the crimping operation has been completed the operator raises the handle 34 and permits reengagement of the latch 31 with the shoulder 30 so that the crimping mechanism is supported in the suspended and non-operative position. The frame 23 is swung around upon the fixed standard 21, and the pail P is lifted by its bail. The hook 25 is brought over in engagement with the frame 23 when it is desired to hold the frame rigid, as for exam le when moving the apparatus over the cor from place to place.

While the construction and arrangement of the improved apparatus for fastening pail receives the crimping mechanism-standard I for guidance, a handle swingably attached to the frame for operating'the crimping mechanism, a head having trunnions applied to the handle thereby to carry the crimping mechanism, said head having a flanged sleeve swivelly supporting said flanged collar, and a latch carried by the handle being engageable .with the boss to suspend the handle and crimping mechanism, said handle carrying means to operate and release the latch at times.

2. Apparatus of the character described comprismg a pail supporting base, a rigid standard uprising therefrom, an arm havm a sleeved end swivelled on said standard an providing a supporting and guiding frame, a fixed collar on said standard upon which the base of said sleeved end is supported for swinging movement of its arm in a horizontal plane transversely of said base, a cover crimpin head guided on said frame for movement 1n a vertical plane toward and from said base, a lever pivoted to said head and fulcruming on said frame for effecting cover crimping operation of-said head by its downward movement and vertical head a lifting movement by its upward-movement, said lever also providing means for effectin bodily swinging movement of the raise crimping head with said-swivelled frame in 'a'; horizontal plane transversely of the base, with means for latching the head, when ele vated, to said frame.
